Abstract
Abstract Minicomputer including a computing unit, numeral, function and clearing inputs, a fixed-program memory and selectively freely-programmable memories, and a readout or display unit including a selector switch for calculating and converting in two systems of units selectively connectible to the fixed-program memory and the computing unit, the fixed-program memory having means for storing and reading out conversion factors and, selectively inverse values thereof as well as a corresponding dimension, the fixed-program memory having a respective input connected to a factor selection unit and to a call-up unit for the dimension of the respective selected factor and inverse value, and having a respective output connected to the computing unit and to the readout or display unit.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
194 words
Minicomputer for converting values, especially of a medicinal nature, between two systems of units, the minicomputer having manually actuatable numeral, letter, function and clearing keys, a computer unit having computing circuits responsive to numeral, function and clearing keys, respectively, a readout or display unit, respectively responsive to actuation of the keys and the computing circuits, and a fixed program memory wherein calculating routines and conversion factors for the calculation and conversion, respectively, between the two systems of units are stored whereby, upon actuation of a function key, one of the stored conversion factors is addressed thereby and entered from the fixed-program memory into a register of the computer unit, the improvement comprising means in the fixed-program memory for storing not only the conversion factors but also dimensions pertaining thereto in the form of letters, an interlinking logic operative upon actuation of a plurality of letter keys for selectively addressing the respective memory locations for the medical conversion factors and the dimensions pertaining thereto, and a call-up unit operative upon actuation of one of the function keys for display of the dimensions to cause the memory to issue the addressed dimension to the display unit.
Claim 2
Dependent Claim
194 words
Minicomputer for converting values, especially of a medicinal nature, between two systems of units, the minicomputer having manually actuatable numeral, letter, function and clearing keys, a computer unit having computing circuits responsive to numeral, function and clearing keys, respectively, a readout or display unit, respectively responsive to actuation of the keys and the computing circuits, and a fixed program memory wherein calculating routines and conversion factors for the calculation and conversion, respectively, between the two systems of units are stored whereby, upon actuation of a function key, one of the stored conversion factors is addressed thereby and entered from the fixed-program memory into a register of the computer unit, the improvement comprising means in the fixed-program memory for storing not only the conversion factors but also dimensions pertaining thereto in the form of letters, an interlinking logic operative upon actuation of a plurality of letter keys for selectively addressing the respective memory locations for the medical conversion factors and the dimensions pertaining thereto, and a call-up unit operative upon actuation of one of the function keys for display of the dimensions to cause the memory to issue the addressed dimension to the display unit.
Claim 3
Dependent Claim
22 words
Minicomputer according to claim 1 including selector switch means for selecting the direction of the conversion between the two systems of units.
Claim 4
Dependent Claim
20 words
Minicomputer according to claim 2 wherein said selector switch means is a three-position-switch for also turning-on and shutting-off the minicomputer.
Claim 5
Dependent Claim
32 words
Minicomputer according to claim 2 wherein the computer unit comprises a computing circuit with a multiplier, a divider and a register and said selector switch means are connected to the computer unit.
Claim 6
Dependent Claim
30 words
Minicomputer according to claim 2 wherein the computer unit comprises a computing circuit with a multiplier and a register and said selector switch means are connected to the fixed-program memory.
Claim 7
Dependent Claim
24 words
Minicomputer according to claim 1 including a readout key actuatable for performing the computing operations and for activating the display and readout units, respectively.
Claim 8
Dependent Claim
53 words
Minicomputer according to claim 1 wherein the fixed-program memory has a first part thereof for containing the conversion factors, said first part being connected to the computer unit, and the fixed-program memory has a second part thereof for containing the dimensions, said second part being connected directly to the readout or display unit.
